Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

My transistor is the NE4210S01, bias point
VDS = 2 V, ID = 10 mA and at 6 GHz.
I'm doing an availabe gain
(Ga) design, keeping my load complex conj of the output reflection,
and draw the constant gain circles in the GammaS plane:
that the gain circle corresponding to the MSG has some parts inside
the stable region. Picking values of GammaS so that I have higher gain
than the MSG, I get some GammaL according to the perfect match at the
output - and this is also in the stable region! So I have stability
both at the input and the output, even though choosing points on having
higher gain than the MSG!
Can this be, and if so - why oh why?
